Measuring stopper for bottles



Oct. 22, 1935. A. BERENDT MEASURING STOPPER FOR BOTTLES Filed Oct. 7,1955 INVENTOR. 19 Befienaf- BY 3 A TTORNEY Patented Oct. 22, 1935 UNITEDSTAT 1 Claim.

One object of this invention is the provision of a stopper for bottlesor flasks by means of which a given quantity of the liquid contents ofthe bottle may be poured out by a single tilting of the bottle, the flowautomatically stopping when the given amount has passed out.

Another object of the invention is the provision of a bottle stoppersuch as above-mentioned with means for automatically closing the bottleoutlet when the bottle is returned to its upright position after aquantity has been poured therefrom.

A further object of the invention is the provision of a detachable meanswhich may be applied to a stopper of the ordinary type of cork or rubberstopper, to convert said stopper into a measuring stopper of the kindabove-mentioned.

The above and other objects will be come apparent in the descriptionbelow, in which characters of reference refer to like-named parts in thedrawing.

Referring briefly to the drawing, Figure l is an elevational view of abottle equipped with the measuring stopper.

Figure 2 is a fragmentary cross-sectional elevation-al view of the same.

Figure 3 is a view similar to Figure 2 showing the bottle in tiltedposition.

Figure 4 is a cross-sectional view through the stopper.

Figure 5 is a, plan view of the stopper.

Referring in detail to the drawing, the numeral I represents a bottlehaving the neck H. Within the neck I l is mounted a removable stopper l2of any desirable material, the same being provided with a flanged top I3adapted to overlap the neck of the bottle.

The stopper is provided with an axial bore M in which a cylindrical tubeI is mounted. Both ends of the bore It are bevelled to accommodate theoutwardly-curved peripheries of the tube l5.

The ends of the tube l5 are slitted to form spaced-apart tongues 2|, thelatter after the tube has been mounted in the bore M, being bentoutwardly to provide a tapering seat for the valve-like members about tobe described.

A length of cord or other flexible string passes through the tube l5,and at each end is secured a pear-shaped member l6 and H, which may beformed of rubber and may be provided with a weight-like core 18. Thecord I9 is attached to these members in such manner that the narrowerends of the members face each other, and it is of a length slightly lessthan that of the tube l5. In order to prevent opening of the bottleduring transit or before it is brought into the household for use, aseal of any desirable material such as Cellophane, is provided, as shownat 20.

When the filled bottle stands upright, the upper member I6 is weighteddown by the mem- .5 her I! to close the mouth of the tube l5. When thebottle is tilted to the position shown in Figure 3, the liquid will flowinto the tube and fill the latter, the member It} still closing thetube. When the bottle is tilted furthenthe weighted 10 member It willfall from its position in; the mouth of the tube and thereby permit theoutflow of the liquid contained within the tube. At the same time,however, the weight of the member l6 causes the member I! to be pulledagainst the lower entrance of the tube, thus preventing any more liquidfrom flowing from the bottle into the tube. Hence no more than theamount of liquid equal to the colume of the tube, or slightly in excessthereof, will flow from the bottle upon single tilting of the bottle.

When it is desired to convert an ordinary cork or rubber stopper intosuch a measuring stopper,

a hole is first bored through the stopper. The tube IS, with its endsmerely slitted as abovementioned without bending the tongues 2i back,

is then inserted into the bore, with the cord I9 having the members Itand l? attached thereto, and finally the tongues 2! are bent back asabove-described, thus providing the seats for said members and at thesame time locking the tube l5 in the stopper.

For different quantities to be poured at a single tilting of the bottle,the length of the tube may be varied according to the quantity desired.

Obviously other modifications in form and structure may be made withoutdeparting from the spirit and scope of the invention.

I claim:

A bottle stopper having an axial bore therein, a tube mounted in saidbore and having its ends outwardly flared to form tapering seats, aflexible string passing through said tube, and a pearshaped valve membersecured to each end of said string, the upper of said members seating inthe upper of said seats when the bottle containing the stopper isupright and the lower of said members being suspended at a distance fromthe lower of said seats, tilting of the bottle from the upright to thehorizontal position causing the lower of said members to fall againstthe lower rim of said stopper and said string being thereby bent aroundsaid lower seat, said lower member thereupon lying in a, positiondownwardly inclined from the axis of the main body of said 5 string topermit a wide opening of the lower end of said bore.
